What is SSL?

The Secure Sockets Layer (SSL) and Transport Layer Security (TLS) is the most widely deployed security protocol used today. It is essentially a protocol that provides a secure channel between two machines operating over the Internet or an internal network. In today’s Internet focused world, the SSL protocol is typically used when a web browser needs to securely connect to a web server over the inherently insecure Internet.
Technically, SSL is a transparent protocol which requires little interaction from the end user when establishing a secure session. In the case of a browser for instance, users are alerted to the presence of SSL when the browser displays a padlock, or, in the case of Extended Validation SSL, when the address bar displays both a padlock and a green bar. This is the key to the success of SSL – it is an incredibly simple experience for end users.

What is an SSL Certificate?

SSL Certificates are small data files that digitally bind a cryptographic key to an organization’s details. When installed on a web server, it activates the padlock and the https protocol (over port 443) and allows secure connections from a web server to a browser. Typically, SSL is used to secure credit card transactions, data transfer and logins, and more recently is becoming the norm when securing browsing of social media sites. SSL Certificates bind together:

A domain name, server name or hostname.
An organizational identity (i.e. company name) and location.

An organization needs to install the SSL Certificate onto its web server to initiate secure sessions with browsers. Depending on the type of SSL Certificate applied for, the organization will need to go through differing levels of vetting. Once installed, it is possible to connect to the website over https://www.domain.com, as this tells the server to establish a secure connection with the browser. Once a secure connection is established, all web traffic between the web server and the web browser will be secure.

What type of SSL do I Need?

Domain SSL

  • Secure a single domain for business user

  • Only domain details are shown in the certificate.

  • Quick issuance (Under 5 Minutes)

Domain SSL certificates are issued quickly and validate that you own the domain. Domain SSL's are a great way to get started with SSL quickly and make sure your visitors’ browsing activities are protected. However they do not include business credentials in the certificate like Extended SSL and Organization SSL certificates

Organization SSL

  • High Assurance SSL

  • Secure a single domain for business user

  • Organization details are show in certificate

Organization SSL certificates include business information to let visitors know that your site is belongs to your business, and is not a phishing scam.

Extended SSL

  • Maximum security

  • Visible trust with green address bar

  • Organization detail shown in certificate

Every visitor will know that your site is encrypted when the green address bar shows up with your organization name displayed prominently. Extended SSL is what the major financial institutions and large retailers have on their pages. Extended SSL certificates are posted to Certificate Transparency Logs so that Public Audit Records can be checked for maximum trust.

Verify Domain Ownership - Approver Email Method

Domain SSL Certificates are authenticated using the Approver E-Mail verification system.
The following email addresses can be used for domain approval:

The current whois admin contact
The current whois technical contact

You must have access to one of these email accounts on the SSL domain to be able to receive the SSL certificate.

Common Name

The Common Name is typically composed of Host + Domain Name and will look like "www.example.com" or "example.com".


If you lose your private key and cannot install your SSL certificate you can receive a new certificate free of charge.

Wildcard SSL

Overview of Using a Wildcard SSL Certificate

A single Wildcard SSL certificate can secure multiple websites. Typically, a standard secure server SSL certificate is issued to a single FQDN. This means that the certificate can only be used on the exact domain to which it has been issued. The Wildcard SSL option, when activated, allows you to circumvent this restriction by receiving a Wildcard SSL Certificate issued to "*.domain.com". The (*) character replaces a fixed sub-domain with a variable one.

Public IP Addresses

Issuing an SSL Certificate to a Public IP Address

An SSL certificate is typically issued to a Fully Qualified Domain Name (FQDN) such as "https://www.domain.com". However, some organizations need an SSL certificate issued to a public IP address. This option allows you to specify a public IP address as the Common Name in your Certificate Signing Request (CSR). The issued certificate can then be used to secure connections directly with the public IP address
